摘　　要：The static adsorption of xenon on active carbon fiber (ACF) at 257 K was measured with ASAP2010 specific surface area and pore diameter distribution instrument by changing the working gas from nitrogen to xenon. Compared with grain activated carbon (GAC), the results were as follows: (1) The adsorption performance of Viscose-based ACF (VACF-As) was the best among all absorbents tested. VACF-A3 was the superior xenon absorbent. The performance of pitch-based ACF (PACF-Cs) approached that of GAC, (2) Due to the difference of aperture distribution, the adsorption performances of ACF with different radics were different under the same experiment conditions even though the specific surface area was similar, (3) There were some differences of adsorptive capacity among ACF absorbents which had the same radic, however there was not definite relationship between their specific surface area and adsorptive capacity, (4) The adsorption of xenon on all kinds of ACF agrees with Langmuir equation, (5) The adsorptive curves can be fitted with a binomial equation. 关键词：碳纤维氙吸附 ACF CTBT
